JOHN E. SOHMALZ, OF NEV YORK, N. Y.

MACHINE' FOR CUTTING CIGAR-WRAPPERS.

SPECIFICATION forming part of Letters Patent. No. 364,774, dated June 14, 1887 Application tiled February 8, 1887. Serial No. 526,898. (No model.)

yments being designed with a view to facilitate the cutting out ot'the different sizes and shapes of the'wrappers, and especially for facilitating the cutting of the wrappers from tine and tender leaves, in which it is necessary to start the cuttingot the wrapper at the tip end, in contradistinction from my former patent, in which the cutting action commenced at the butt-end and terminated at the tip end.

For this purpose the invention consists', tirst. in a machine for cutting cigarwrappers in which the cutter or knife is pivoted at both ends to spring-actuated sliderods guided in fixed' and slotted standards, sothat the cutter can be lowered either at its .tip end orat the butt-end, as desired`,`the slide-rods being actuated by independent treadles and intermediate v spring-actuated connecting-rods.

The invention consists, secondly, of an iinproved construct-ion of the hollow cutter in which the curved t'rontblade is capable of adjustment toward the straight and stationary rear blade, so as to produce wrappers of different sizes and shapes.

In the accompanying drawings, Figure 1 represents a-sectional front elevation of my improved machine for cutting ci gar-wrappers, showing the cutter in its normal posit-ion. Fig. 2 is a vertical transverse section ot' the same on line xx, Fig. 1.' Figs. 3 and 4 are front elevationsshowing the cutter at both ends of its stroke. Fig. 5 is a plan of the machine, partly in horizontal section,througl\i the guidestandards. Fig. 5 is a detail section showing the pivot-connection of the cutter. Fig. 6 is a bottom View of the cutter, drawn on a -larger scale; Fig. 7, a vertical transverse section of the same on line y y, Fig. 6; and Figs. 8, 9, 10, and 11 show different shapes of the wrappers which can be cut by my improved cutting-machine.

vthe top with a zinc plate, D'.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the supporting-stand, and B the table, of my improved cigarwrappercutting machine. On the table B are supported t-wo upright transversely braced and slotted standards, C G, and between theY same a block, D, that is covered at In front ofthe block D is arranged a plate, E, on which the wrapper is first spread preparatory to being transferred to the block D.

In the slotted standards C C are guided double T-shaped crossheads j', which are attached to the upper ends of guide-rodsf, that extend downward through the standards C C, and are connected at their lower threaded ends by socket-nutsfz, having interior right and left hand threads, and with the threaded upper ends of spring-actuated connecting-rods f3, which are guided in eyes of the supporting-frame A, and pivoted at their lowerends to treadles F F, said treadles being pivoted to a transverse bottom rod, f4, of the frame A, as shown clearly in Fig. 1.

Between the cross headsv j of the slotted standards C C and the contracted bottom portions of the same that extend below the table B are interposed spiral springs that serve to support the cross-heads in their normallyraised position, and return them into this position whenever they have been lowered by depressing the treadles F. 'Io forwardextending pivots of the cross-headsff is appied the cutter G by means of a round eye, g, at one end and a slotted or elongated eye, g', at the other end, which latter permits the setting of .the cutter G in an inclined position toward the block D by a sliding motion imparted to theM slotted eye g on the pivot of its cross-head .d

f whenever the cutter G is changed from its normal horizontal position (shown in Fig. 1) to an inclined position by the action of the treadles, as shown in Figs. 3 and 4. The eyes g g' of the cutter G are retained on the pivoted ends of the cross-heads f f by washers g2 and screws g3, as shown in Figs. 1, 2, and 5. One of the cross-headsf is further connected with a registering device, R, and by a belt or cord having a weight at the lower end with a pulley on one end of a short transmitting-shaft,

IOO

the opposite end of which carries a bevelwheel that meshes with a second bevelgear on a vertical shaft, which carries at its upper end a fan, as shown in Fig. 2. The fan-shaft turns in bearings of the table and is rotated by the operation of the cutter, the fan serving to agitate the air and to keep off the flies.

The Ventilating-fan is specially useful in the summer season and in warm climates, but forms, like the registering device, no part of the present invention.

The cutter G is made in the form of the cigar-wrapper to be cut from the leaf, and is made in t-he form of a hollow or open-bottomed shell or body, as shown clearly in Figs. 2 and 6. The block D is made of elongated shape and rounded off at the ends, so as to conform to the shape of the cutter and the wrapper to be cut thereon. After the leaf has been carefully spread and smoothed on the front plate, E, it is transferred to the face of the block D and carefully spread over the same, and held in position on the same forinsuring the cutting out of a perfect wrapper. The lower or cutting edge of the cutter G is continuously curved or convex, and provided with a stationary rear blade, G', which is nearly straight, and secured by an angular portion 'to the top plate, G2, of the cutter. The tip end,G3,of the cutter G is made hookshaped, and also attached rigidly to the top plate of the cutter. The front blade, G, is curved and attached to an adjustable angleplate, G5, that is provided with a slot, c, atits middle portion, so as to be adjustable and held by a headed screw-bolt, c', and thumb-nut e2 to the top plate, G2, of the cutter, as shown clearlyin Figs. 6 and 7.

The front cutting-blade, G4, is extended beyond the angle-plate G5, over the tip-block and attached thereto, while its butt-end is also extended beyond the angle-plate G5 toward the stationary rear cutting-plate, with which it contacts at the end, so as to give sufficiently and follow the adjustment of the middle portion of the blade G4, as produced by the adjustable angle-plate D. By the adjustment of the front blade, G, toward the rear blade, G', different widths ot' cigar-wrappers can be cut by the same cutter as required. For different shapes of wrappers, as shown in Figs. 5 to 11, as required by the different styles of cigars, cutters of different shapes are used, which are constructed in the manner described, each cutter being capable of cutting wrappers of different widths.

The operation of the machine is about the same as that of the machine described in my prior patent referred to, but with this difference: that the cutterin the present machine can be lowered either end first at the tip or butt end, according as the cutting action is to commence at the tip or butt end of the wrapper. For cutting wrappers from ne and thin leaves the cutter is lowered trst at the tip end by depressing first the left-hand treadle, as shown in Fig. 3, after which the right-hand treadle is depressed and the cutter lowered at the butt-end, as shown in Fig. 4, so as to complete the cutting of the wrapper at the middle portion and butt-end. Simultaneously therewith the left-hand treadle is released and the tip end returned to its normal position. blades of the cutter produce a draw-cut that commences at the tip end and terminates at the butt-end of the wrapper, whereby a perfect wrapper is produced. When the cutting operation is completed, the right-hand treadle is released and the butt-end of the cutter returned into its normal raised position. The wrapper is then removed from the block D and the machine is ready for the next cutting action.

Having thus described my invention, I clai 1n as new and desire to secure by Letters Patent- 1. The combination ofupright slotted standards, spring actuated cross-heads guided in said standards, a cutter or k nifc having a continuously curved or convex cutting-edgeconforming to the shape of the wrapper to be pro- 9o i duced, said cutter having a round eye at one end and a slotted eye at the opposite end by which the cutter is pivoted to said cross-heads, a treadle mechanism connected to each crosshead for depressing either end of the cutter, and a block arranged below said cutter, substantially as set forth.

2. In a cigar-wrapping machine, an openbottomed cutter having a stationary rear blade, a stationary hook-shaped tip end, an adjustable front blade attached at one end to the stationary tip end, and means for adjusting said front blade relatively to the stationary rear blade, substantially as set forth.

3. In a cigar-wrapper-cutting machine, an open-bottomed shell-shaped cutter having a stationary rear blade, a hook-shaped tip end, a front blade attached at one end to the stationary tip end and at its middle or belly portion to an ad j ustable angle-plate beyond which the butt-end of the blade extends, and means for adjusting said angle-plate on the top plate of the cutter, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
